Steering device

Abstract

Provided is a steering device including an inner pipe, an outer column including a holding main body section and a clamp section, a fixed bracket including fixed side sections, a stopper bracket including a movable guide section firmly attached to the inner pipe, and attachment sections formed at front-back-direction both ends of the movable guide section, and a hanger bracket in which sections to be attached to both the attachment sections are formed on front-back-direction both sides, the hanger bracket including side plate sections which sandwich width-direction both side surfaces of the clamp section and in which long holes for telescopic adjustment are formed. The attachment sections of the stopper bracket and the sections to be attached of the hanger bracket are firmly attached and joined by joining members.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a steering device including a telescopic adjustment mechanism, the steering device having satisfactory telescopic operability by reducing a harmful effect of shape deformation in weldbonding and improving assembly accuracy.[0003]2. Description of the Related Art[0004]In general, in a steering device including a tilting / telescopic mechanism, a part where components are bonded by welding is present in the structure thereof. For example, in Japanese Patent Application Laid-Open No. 2009-029224, a distance bracket, in which a long hole for telescoping is formed, and an upper jacket are welded. Further, in Japanese Patent Application Laid-Open No. 2008-100597, a bonding support bracket mounted with a second friction plate, in which a telescopic long hole is formed, is welded to an inner column.[0005]Specifically, Japanese Patent Application Laid-Open Nos. 2009-029224 and 2008-100597 are gener...

AI Technical Summary

Benefits of technology

[0012]Therefore, it is an object of the present invention to provide a steering device that has satisfactory telescopic operability by reducing a harmful effect of shape deformation in weldbonding and improving assembly accuracy.

[0017]In the present invention, the hanger bracket is mounted on the stopper bracket, which is firmly attached to the inner pipe by welding, by the joining members such as pins or screws rather than welding. Since the hanger bracket is not firmly attached by welding, distortion and deformation due to thermal effect do not occur. It is possible to maintain parallelism of both the side plate sections in which the long holes for telescopic adjustment are formed. Consequently, it is possible to perform satisfactory telescopic operation. Assemblability is improved. Further, it is possible to fix a lever load during lever fastening.

[0018]By mounting the hanger bracket with the joining members such as pins or screws, during assembly of the hanger bracket, it is possible to mount the hanger bracket in a position where dimension fluctuation of peripheral components is absorbed. Consequently, even when distortion or deformation due to thermal effect occurs in the stopper bracket and when there is a dimension error of the peripheral components, it is possible to mount the hanger bracket in an appropriate position. It is possible to maintain satisfactory tilting / telescopic operability. Further, it is possible to prevent the rotation of the inner pipe with the hanger bracket.

Problems solved by technology

Therefore, it is likely that distortion or deformation occurs in the distance bracket (4) because of thermal effect during welding work.

Feeling during telescopic adjustment is deteriorated.

Further, assemblability of components is deteriorated.

Therefore, as in Japanese Patent Application Laid-Open No. 2009-029224, it is likely that distortion or deformation occurs because of thermal effect during welding work.

Therefore, it is likely that feeling during telescopic adjustment is deteriorated.
